陶瓷废水处理原理及常用固液分离方法比较

本文就陶瓷废水的产生来源及废水处理原理进行了分析，对佛山市该行业废水处理常用的固液分离方式进行了处理效果及技术经济比较，指出将常用于给水处理工艺的水力循环澄清池应用在陶瓷废水处理工艺中，与其它分离方法相比，不仅占地面积小，效率高，而且易于操作和控制，可实现废水的全部回用，并建议对这种高悬浮物、高浊度水的混凝反应过程进行自动控制以提高水处理的稳定性。

论环境自卫权

环境自卫权是环境权的组成部分,环境自卫权及随着环境权的确立而提出来的,环境权作为环境法的核心问题,近年来在国内外的理论界和立法上都有不同程度的反映,使得环境自卫权的实现也就不可避免的带有复杂性,除了必须具备的条件外,环境自卫权的实现还应当注意实施的手段及其相应性的标准,本文就环境自卫权的生成原因、界定、构成及其实现作了初步研究。     

组织支持感对建筑业农民工不安全行为的影响*

为对建筑业农民工的不安全行为进行科学有效的管理,探讨组织支持感、自我效能感与建筑业农民工不安全行为之间的关系,防止因建筑业农民工不安全行为造成的不安全事件发生,从组织行为学和计划行为学视角出发,以218名一线建筑业农民工为研究对象,通过构建结构方程模型进行实证分析。结果表明:组织支持感的3个维度均可直接对建筑业农民工的不安全行为产生负向显著影响,其中关心利益维度影响最大,工作支持维度次之;建筑业农民工的自我效能感在其组织支持感与不安全行为的负向关系中起到中介作用。     

长江河口近岸水体自然净化作用及其初步评价

按照水体的净化机理，结合长江口和上海滨岸带近岸水体的物理、化学和生物等因素的实际特征，对近岸水体的自然净化作用进行了阐述和分析。并在历史资料和实测资料基础上，就近岸水体的自然净化作用进行了评价。评价结果表明，因长江河口近岸水体存在较强的自然净化作用机制，近岸水体体的自然净化能力较强，环境容量较大，但由于污染物输入量的不断增加，部分岸段近岸水体的环境质量有逐渐下降的趋势；近岸水体的自然净化作用具有明显的季节性变化，长江口南岸水域洪水季节水体的自然净化作用比估水季节强，而杭州湾北岸水域的自然净化作用表现为相反的变化趋势，因此建议在近岸污水排放过程中应考虑近岸水体的净化能力，遵循水体的自然净化作用规律。     

Hannah Arendt’s turn to the self and environmental responses to climate change paralysis

Environmentalists have struggled with how to mobilize people to act in the face of widespread and now inevitable consequences of climate change. Significant responses to this challenge, such as incentivizing individual Green choices in the market and avoiding the rhetoric of catastrophe, continue the philosophical and political trends, identified by Hannah Arendt, that contribute to world alienation and the decline of politics. Environmental thinkers are invited to use Arendt’s theories of the turn to the self and political action to think critically about contemporary strategies to address climate change.     

Development of controlled release formulations of azadirachtin-A employing poly(ethylene glycol) based amphiphilic copolymers

Controlled release (CR) formulations of azadirachtin-A, a bioactive constituent derived from the seed of Azadirachta indica A. Juss (Meliaceae), have been prepared using commercially available polyvinyl chloride, polyethylene glycol (PEG) and laboratory synthesized poly ethylene glycol–based amphiphilic copolymers. Copolymers of polyethylene glycol and various dimethyl esters, which self assemble into nano micellar aggregates in aqueous media, have been synthesized. The kinetics of azadirachtin-A, release in water from the different formulations was studied. Release from the commercial polyethylene glycol (PEG) formulation was faster than the other CR formulations. The rate of release of encapsulated azadirachtin-A from nano micellar aggregates is reduced by increasing the molecular weight of PEG. The diffusion exponent (n value) of azadirachtin-A, in water ranged from 0.47 to 1.18 in the tested formulations. The release was diffusion controlled with a half release time (t_1/2) of 3.05 to 42.80 days in water from different matrices. The results suggest that depending upon the polymer matrix used, the application rate of azadirachtin-A can be optimized to achieve insect control at the desired level and period.     

Work–family conflict and mindfulness: Investigating the effectiveness of a brief training intervention

This experimental switching replications design study examined the effectiveness of a brief mindfulness‐based training intervention that included a one‐hour mindfulness‐based workshop followed by 13 days of behavioral self‐monitoring (BSM) in an attempt to reduce work–family conflict. The intervention increased participants' mindfulness and decreased work‐to‐family conflict, but did not reduce family‐to‐work conflict. In addition, those who participated in BSM reported greater mindfulness, less work‐to‐family conflict, and less family‐to‐work conflict than did those who did not participate in BSM. Theoretical and practical implications, as well as future research directions, are discussed. Copyright © 2017 John Wiley & Sons, Ltd.     

Serving one another: Are shared and self‐leadership the keys to service sustainability?

Service has received increasing attention in the management literature, yet sustainability of service is often overlooked. In this Incubator we examine the potential for client involvement through shared and self‐leadership to foster empathy enhanced service and reduced costs, both of which may support a more sustainable service delivery process.
